Singlephase powders of Ba4Y3F17:Yb:Pr solid solutions with an average agglomerate size of 400 nm were synthesized by coprecipitation from aqueous solutions. It was shown that the down-conversion mechanism in the investigated samples was quantum cutting, with one photon absorbed by Pr3+ ions resulting in two photons emitted by Yb3+ ions. At first, overall the external quantum yield of down-conversion luminescence measured appeared to be relatively high, with a maximum value of 2.9 % for the Ba4Y3F17: Pr(0.1 %):Yb(10 %) sample. It makes this compound promising for Si-based solar cells efficiency enhancement.
Keywords: synthesis, down-conversion, luminescence, solid solutions, photonics, fluorides.
